ACTION-BRACKET FOR PIANOS.

SPECIFICATION forming part of Letters Patent No. 728,192, dated May 19, 1903.

Application filed March 18, 1903.

To all whom it may concern:

Be it known that I, EDWARD BORNHOEFT, a citizen of the United States, residing at New York city, (Bronx,) county of New York, and State of New York, have invented certain new and useful Improvements in Action-Brackets for Pianos, of which the following is a specification.

This invention relates to an action-bracket for pianos which is light, of great strength, and permits the ready attachment thereto of the various parts of the action.

In the accompanying drawings, Figure 1 is a side view of my improved action -bracket; Fig. 2, a front view thereof; Fig. 3, a crosssection on line 3 3, Fig. 1; and Fig. 4:, a longitudinal section through the supportingscrew.

The body of the bracket is made T-shaped in cross-section, being composed of a flat-undulating base 66 and of a web ct, projecting centrally therefrom. At its top the web a is flattened to form a lug 0, which lies closely against the upper portion of base Ct. A perforation (t in the lug a and underlying portion of base a serves for the reception of a bolt, by means of which the bracket is secured to the wrest-plank. At its bottom the base a, as well as the web a, tapers to a blunt point which has a bearing in the concave head of a screw 5, by means of which the bracket is secured to the key-bottom. To the rear side of base a are attached the springrail 0, the action-rail d, and the tongue-rail e, as usual.

To the web a is secured the arm f, which constitutes the support for the hammer-rail.

This arm is composed of two halves or sec- Serial No. 148,295- (No model.)

transverse rivets f. By this attachment between bracket and arm a very firm and reliable connection is obtained. At its upper or free end the arm is provided with laterallyextending flanges f upon which the hammer-rail is adapted to besupported.

My improved action-bracket is light, of great strength, permits the ready attachment of the various parts of the action thereto, and may be readily mounted within the case.

What I claim is.

1. A T-shaped action-bracket for pianos, combined with rails attached to the base of the bracket, and an arm attached to the web of the bracket, substantially as specified.

2. A T-shaped action-bracket for pianos, combined With a flanged bifurcated arm that straddles the bracket-web, and means for securing the arm to the bracket, substantially as specified.

3. A T-shaped action-bracket for pianos having a web that is flattened at its upper end and tapering at its lower end, substantially as specified.

4:. A T-shaped actiombracket for pianos having a flattened perforated upper end, a tapering lower end, combined with a flanged bifurcated arm that straddles the bracketweb, substantially as specified.

Signed by me at New York city, (Manhattan,) New York, this 17th day of March, 1903.
